rIhis invention relates to stoves, and has special reference to stoves used for cooklng purposes and burning gas as a fuel.

Objects of the invention are: to provide a stove :including a broiler oven, and a baking oven in communication with the broiler oven, and burners for the respective ovens having gas supply control valves, in combination With means for holding one of said valves In closed position automatically and as an in# cident to the opening of the other valve so as to prevent simultaneous supply of gas to the two oven burners; and to provide every other novel and improved feature herein disclosed and claimed, reference being made to the accompanying drawings in Which Fig. 1 is an end elevation.

Fig. 2 is a front elevation of the stove.

The stove may be supported by the legs 1. A gas supply pipe 2 opens into a manifold 3 at the front of the stove and has valve devices 4 for controlling and regulating the passage of gas from the manifold 3 to the burners on the top of the stove.

The door 7 9 aords access to a space comprising a broiler oven and a baking oven. The inside construction of these ovens is not l shown. that being unnecessary in order to comprehend the present invention. Each oven is, of course, provided With a gas burner (not shown) to one of Which gas is supplied through a pipe 91 controlled by a valve 92 and to the other of Which gas is supplied through a pipe 93 controlled by a valve 94. The pipes 91 and 93 open from the pipe 2 and conduct gas therefrom to the respective oven burners. In the specific embodiment of the invention shown the valves 92V and 94 are capable of being turned from closed to open positions and vice versa.. In closed positions the handles of the valves 92 and 94 extend vertically and in order to open said valves it is necessary to turn the handles of said valves to horizontal position, though this arrangement may be modified.

An arm 95 is supported intermediate of its ends on a pivot 96' and on its upper end is formed With a frame 97 designed and adapted in one position to enclose the valve handle 92; and on its lovver end the arm 95 is formed with a frame `98 designed and adapted lin one position to enclose the valve handle 94. When the frame 97 is in position to prevent opening of the valve 92 the frame 98 is in position to permit the valve 9.4 to be opened; and when the frame 98 is Vin positionto prevent opening of the valve 94 the frame 97 is in position to permit the valve 92 to be opened. So, it-is impossible to open either valve While the other is open, it being necessary to close each valve before the other can be opened, This contributes to safety and prevents explosions resulting from the admission of gas to either burner in the oven While the other burner is burning. This safety device may be mounted on a remov-` able support 99 secured to the end Wall of the stove by bolts `100 andV provided with guides 101 for the arm 95.

. The handles of the valves 92 and 94 iden, tify said valves as of the longitudinally immovable type and which turn from closed `to open positions Without moving longitudi'f' nally. The handles of these valves are shown as being in the form of arms attached to the valves and engageable to turn the valves as required 'to open and to close said valves. The frames 97 and 98 are movable toreeeive thehandles of the valves 92 and 94, I-'espec-y tively,lwhensaidvalves are closed. If either valve be turned to open position, the handle 92 or'94 extends across the corresponding frame 97 or 98 and thereby locks the arm 95j against movement. The arm 95 is thereby held so that it cannot be moved to release or permit opening of the other valve. By this construction, I am enabled to use a single lock device for the valves 92 and 94 even though said valves are Widely spaCed.

From the foregoing it will be apparent that: a stove embodying all of the features shown and `Closcribed obtains all of its in-A tended objects in a highly efficient and desirable manncl- VThe construction and arrange.- ment may be varied Within equivalenti limits Without departure from the nature and principle of the invention.

1. In a gas stove, a gas supply pipe having gas outlets, a rotary longitudinally immovable valve controlling each of said outlets,

an arm handle controlling each of said valves, a support, a pivot carried by said support, an arm mounted on said pivot for 5 swinging movements toward and away from said outlets respectively, and frames supported by said arm for receiving'and engaging said arm handles respectively and permitting both valves to be in closed adjustment and preventing simultaneous opening of said valves.

2. In a gas stove, the combination of a gas supply pipe having gas outlets, a longitudinally immovable valve controlling each of said outlets, an arm handle controlling each of said valves, a support, means for holding said support adjacent to said pipe, a pivot carried by said support, an arm mounted on said pivot for swinging movements toward and away from said outlets respectively, and

frames on said arm for receiving and engaging said arm handles respectively to preventsimultaneous opening of said valves.

3. In a gas stove having a broiler oven and a baking oven in communication with the broiler oven, the combination of a gas supply pipe having gas outlets to supply said ovens respectively, a longitudinally immovable valve controlling each of said outlets, an arm handle controlling each of said valves, a pivot supported between said valves, an arm mounted'on said pivot for swinging movements toward and away from said outlets, and parts on said arm for receiving and engaging said arm handles respectively to prevent simultaneous opening of said valves.

4. In a gas stove having a wall, the combination of a gas supply pipe having a pair of spaced gas outlets, a longitudinally immovable valve controlling each of said outlets, an arm handle controlling each of said valves, a support attached to said wall, a pivot on said support between said valves, an arm mounted on said pivot for swinging movements toward and away from said gas outlets respectively, and parts on said arm receiving and engaging the respective arm handles when the respective parts are away from said gas outlets and being disengaged from said arm handles when the said respective parts are toward said gas outlets.

5. In a gas stove, a wall, a gas supply pipe having a pair of spaced gas outlets, a longitudinally immovable valve controlling each of said gas outlets, an arm handle controlling each of said valves, a pivot supported by said wall between said lgas outlets, an arm mounted on said pivot for swinging movements to locate the ends of said arms respectively in or out of position to engage said arm handles and prevent Opening of Said valves respectively and to permit opening of either valve when the other valve cannot be opened.
